VCDS - Getting Started - Section 1-A
Thank you for purchasing VCDS, which allows you to turn a Windows PC into a powerful
diagnostic tool for VW/Audi/SEAT/Skoda vehicles from 1990 through the latest models.
Read This First!
Before plugging anything in, you must
first install VCDS software on your PC.
Step #1
Go to our website and click on Download at the top of the screen to download and install
the latest version of VCDS:
www.Ross-Tech.com
Run the installation file that you have
downloaded and follow the onscreen
instructions and allow VCDS to
install in its default directory. You will
also be given a screen with several
choices for UBS drivers, it is
recommended to leave these in their
default settings unless instructed
otherwise by Ross-Tech. Make sure
to allow the USB drivers to install
after the main program installation
has finished. ►
The VCDS Pro-Kit comes with a CD containing our software as well. If possible it is always
a good idea to download the latest version from our website.
◄Step #2
Connect the USB end of your
USB Interface or the Serial end of
your Serial Interface to the correct
port on your PC. If your PC is
further from the vehicle’s
diagnostic port than 6 feet,
connect an approved Extension
Cable between the PC and the
Interface. The appropriate
extension is included in the ProKit and additional ones are
available from our web store.
Getting Started - Section 1-B
Step #3 (USB Only) ►
If you are using a Serial Interface then you can
proceed to step #4. If you are using a USB
Interface, a message like this should pop up: ►
The drivers many install automatically in Windows 7 or Vista. If you are using XP or W2000,
click on the Found New Hardware message and the Found New Hardware Wizard should
start up. If you are prompted with the choice, pick “No, Not This Time” when asked if you
want to connect to the Internet to search for drivers. Select "Install the software
automatically (Recommended)" then click [Next >]
The process should be automated but you may need to click “Continue Anyway” part way
through the process.
If, for some reason, you installed the USB Interface without following the above
instructions, and VCDS does not work correctly, go into your PC’s Device Manager while
the USB Interface is connected.
You can find the Device Manager by right-clicking on My Computer in XP or on Computer
in Vista or 7. Select Manage to bring up Computer Management. On the left side of the
screen under System Tools, select Device Manager.
Find the “VCDS Compatible USB Interface” or similar and delete it. It may be under “Other
Devices” or under “Universal Serial Bus Controllers”. Next, unplug the USB Interface from
your PC, wait 5 seconds and plug it back in. Proceed with the installation starting on Step
2.
Step #4 ►
Connect the car end of your
Interface to your vehicle’s Diagnostic Port. ►
◄ If your vehicle has a 2x2 port (some pre-1996
vehicles), then use the optional 2x2 Adapter between
the Interface and the ports in the car. This is included
in the Pro-Kit.
Turn the vehicle’s ignition switch to the ON position. Make sure the key is turned far
enough that the dash lights are fully illuminated. The engine may either be running or
stopped.
Getting Started - Section 1-C
Step #5 ►
Start the VCDS program on your PC through either the Start
Menu or the VCDS icon on your Desktop.
◄ Step
#6
From the Main
Screen in VCDS
click the [Options]
button to go into
the Options screen.
Step
#7►
Once you are in the
Options Screen,
Select the correct
port for your PC’s
USB Port (USB) or
Serial Port (typically
COM1 or COM2)
and click the [Test]
button. Ensure that
VCDS finds your
interface.
Getting Started - Section 1-D
Step #8 ►
You should see a message like this:



If the Interface Status is “Not Found!”,
check the connections at the car and PC.
Make sure both are plugged in securely.
Serial Interfaces get their power from the
vehicle so they will not be recognized at all
if not plugged into a car.
Adapter Type should always be “RossTech” followed by the name of the
Interface such as “HEX-USB+CAN”.
Version indicates the firmware version of
your Interface. It may be updated by new
versions of VCDS, if so follow the prompts
on the screen.
Interface Name:
Expected Test Result:
K1: OK
K2: OK
CAN: OK (when tested on a car with CAN)
CAN: Not Ready (on cars w/o CAN)
K1: OK
K2: OK
CAN: Not Supported
K1: Not Supported
K2: Not Supported
CAN: OK (when tested on a Mk5 based car with CAN)
HEX-USB+CAN,
HEX-COM+CAN
KII-USB, KEY-USB,
KEY-COM,HEX-USB,
HEX-COM
Micro-CAN
If K1 or K2 status are ”Short to Ground” or “Short to +12V” then you may have a short or an
open circuit in the car’s diagnostic port, often caused by the Aftermarket Radio Problem,
See this page on our website for more info:
http://www.ross-tech.com/vag-com/aftermarket-radio.html
Once you have tested successfully, click [OK] then click [Save] to apply this configuration,
you will be returned to the Main Screen. Click on [Select] to view the Select Control
Module Screen. Select one of your car's Control Modules such as Engine.
Note: Your car will not have all the Control Modules listed in VCDS, only the functional
ones that were installed in your vehicle. See the Applications Page for your car on our
Website for more info:
www.Ross-Tech.com/vag-com/cars/applications/
After VCDS has connected, click on [Fault Codes] to check for Fault Codes (DTCs).
Repeat the process for each of your car's Control Modules. If you encounter problems, see
the FAQ on our website first:
If you still have problems, feel free to contact us with full details about your PC and vehicle,
preferably while you are in front of both:

VCDS - Main Screen - Section 2-A
This screen appears when you start VCDS by clicking the shortcut on your Desktop or by
selecting VCDS from the Start Menu. These screen-shots were taken using Microsoft
Windows 7 with the "Aero" style. If you are not using 7 Aero, expect the screens to look
different but the functions will be the same.
On this screen, you have 8 buttons that you can click:
[Select]
(see Section 4 of this manual)
[Auto-Scan]
[SRI Reset]
[OBD-II]
[Applications]
[Options]
[About] (see Section 31 of this manual)
Each of the above buttons is described in its own section in this manual.
[Exit] (This closes the VCDS program)
VCDS – Auto Scan - Section 3-A
(VAG 1551/1552 function 00)
This function scans each controller in the vehicle to retrieve controller information - VAG
Part Numbers, Component number, Soft. Coding, WSC, and fault codes.
Important! AutoScan is probably the single most important function in VCDS. We
recommend that you run and SAVE a complete AutoScan on every single vehicle
that you work on. This will give you a history of the vehicle that can be invaluable in the
future, for example if an ABS module fails and needs to be replaced. Referring back to
earlier Coding is often MUCH simpler than trying to figure out such values from scratch.
First, you must Select Chassis Type:
There are dozens of different control modules that exist across the entire range of VW/Audi
vehicles. No one car has all Modules! Newer cars have more, older cars have fewer.
Because of this, you must select a Chassis Type that contains only those modules that are
plausible for a given chassis. There are some exceptions but in general, the Chassis Type
is the 7th and 8th digits of the VIN number. For example WAUZZZ4F36N111022 has 7th
and 8th digits of 4F and is a "4F,Audi A6 C6". For additional help determining chassis type
see this page on our Website:
If you select Auto Detect (CAN Only) as the Chassis Type on newer cars which have a
fully CAN-based diagnostic system, VCDS can automatically determine which modules are
installed in a particular car and perform an Auto-Scan of exactly those modules. This can
make the Auto-Scan considerably faster.
Auto Scan cont. - Section 3-B
There is a file in the VCDS directory called AutoScan.txt, which contains all of the vehicle
profiles. It can be edited by simply clicking on the hyperlink above the Chassis Type
selection. This will open the file in your default Text editor (like Notepad) to create a custom
profile for your vehicle. To help you figure out which controllers are in your car, you can run
the Control Module Finder in section 28 of this manual.
The Display Freeze Frame Data checkbox adds Freeze Frame data for Fault Codes on
control modules using the KWP-2000 protocols. Not all control modules support this freezeframe data. As a rule of thumb, cars which were re-designed after 2003 will likely have
some control modules which support it, and older designs will not. There's no harm in
leaving this enabled in any case. However, un-checking it can make the results less
cluttered in a scan which contains many fault codes.
[Start]
This begins the Auto Scan. Be aware; this process can take several minutes. While the
scan is running, VCDS will cycle through the Open Controller and Fault Code screens for
each controller before returning to the Auto Scan screen. On newer control modules which
have different Hardware and Software part numbers, Auto-Scan includes the Hardware
Part Number as shown in the screenshots. Once the scan completes, Double-clicking on
any of the Control Module names in RED will open the Fault Codes screen for that
controller and allow you to clear the codes.
[Stop]
This stops the Auto-Scan.
The Auto-Refresh box can be handy because it can show when a fault code appears in a
particular system.
Auto-Scan cont. - Section 3-C
[Gateway Installation List]
Only available only on Gateways in cars using a direct CAN connection for diagnostics.
This function is also accessible from the Applications Screen. This very fast function takes
about 3 seconds to query the car's Gateway to find out what modules are installed in the
car and what their status is. Any modules having fault codes should show a "Malfunction"
and will be highlighted in RED. Double-clicking on any of the Control Module names in RED
will open the Fault Codes screen for that controller and allow you to clear the codes.
Modules are directly accessible from this screen by double clicking on the appropriate line.
Changes to the Gateway Installation List can be made using the Gateway Coding function
The following screen-shot is from an Audi A6 (C6/4F):
[Clear All DTCs]
This function is only available with our HEX Interfaces and is implemented in two ways.
On pre-CAN-Bus vehicles, VCDS will access each control module and clear DTCs from
each one individually. On vehicles using CAN-Bus for diagnostics, VCDS performs this
function without accessing all the control modules individually. If you are not using a HEX
Interface then you'll need to go into each module that has faults to clear them individually.
This function is also accessible from the Applications Screen. The following warning should
pop up:
Auto-Scan cont. - Section 3-D
The VIN should be retrieved automatically from all cars which "know" their VIN. Also in
control modules that provide it, engine codes and Jxxx component identifiers are shown as
well.
Results:
If you close the Auto-Scan dialog, any data in its output box will be lost. If you would like to
keep a record, click the [Copy] button first, then you can paste the results into the
application of your choice, such as MS Word or Notepad.
[Print]
This function sends the results to your printer.
[Save]
This function saves the results to a text file in our Logs directory, typically in
C:\Ross-Tech\VCDS\Logs\
[Clear]
This erases your results. This does NOT erase the fault codes from any of the controllers.
You'll need to go into each controller to Clear Codes or use the Clear All DTC's function for
that.
To return to the Main Screen, click [Close]
VCDS- Select Control Module- Section 4-A
The various computers in the car are called “Control Modules” or “Controllers”. On this
screen, you select which Control Module you want to "talk" to. To establish communications
with a particular Control Module, simply click on the appropriate button. For example, click
on the button for [01 – Engine] to connect to the engine controller.
Module Tabs: Each tab on the top of this screen contains a number of different controllers
grouped by category. In CAN based cars that have a proper Gateway supporting an
Installation List, VCDS will automatically populate one or more Installed tabs containing
buttons for only those control modules that are actually installed in the car. It does take
about 1.5 seconds to get the list from the Gateway, so a bit of a delay when clicking
[Select] is normal / expected. When used on a car which does not have a Gateway that
supports an Installation List, the old-style Common tab will still be shown. For customers
who use VCDS primarily on older cars which do not have an Installation List available, this
feature can be disabled on the User Interface and Identification tab of the Options screen.
The other tabs are: Drivetrain, Chassis, Comfort/Conv., Electronics 1, Electronics 2,
and LT3. Each possible controller is listed as a number and a description, i.e.,
[01-Engine]. The number corresponds to the controller number that you'd find in your
Factory Repair Manual in the instructions for using a VAG-1551 or other factory diagnostic
tool. VCDS has buttons for all control module addresses currently supported by the factory
diagnostic tools.
Direct Entry: Addresses can be accessed manually - just type the number and click [Go!]
To return to the Main Screen, click [Go Back]
Note: Your car will not have all the Control Modules listed in VCDS, only the ones that
were installed in your vehicle. See the Applications Page for your car on our Website for
more info:
VCDS - Open Controller- Section 5-A
This screen will appear when VCDS is establishing communications with any of the Control
Modules shown on the Select Control Module screen.
Comm Status Shows the status of the current communications session. Once
communications have been established:

IC= Shows the number of times the session has been initialized. If IC increases
beyond 1, communications are less than 100% reliable.

TE= is a counter of transmitter errors within individual packets. TE greater than 0
can indicate unreliable communication.

RE= is a counter of receive errors within individual packets. RE greater than 0
can indicate unreliable communication.

Protocol indicates whether the controller speaks KWP-1281 , KWP-2000 , CAN,
or UDS. Different functions and behavior can be expected depending on which
protocol is used by each controller. VCDS communicates fine with all four of
these protocols.

A rotating cursor shows that communication is active.
Open Controller cont. - Section 5-B
Controller Info
Once the communications session has been established, all of the Control Module’s
"Identification" data is presented here.

VAG Number is the VW/Audi part number for this controller. All of the digits, both
numbers and letters, make up the part number. In some cases this number may
be different from the number on the sticker on the module itself, specifically if the
module has been reflashed by a dealer per a service campaign.

Component contains more identification information about the controller and
may contain a version number for the controller's internal firmware. The firmware
level is also known as the software version for the controller. In the above
example, the software version is 0010 since these are the digits shown at far
right in the Component field.

Soft. Coding is the Software Coding that determines various options for the
controller. Note: Some older Control Modules are not "codeable" and you may
see a Bosch part number or other information in this field.

Shop # identifies the WorkShopCode ( WSC) stored in the scan-tool that
performed the last Coding or Adaptation procedure in this Control Module.

The Extra fields can show VIN and Immobilizer information or slave controller
part numbers in some vehicles.
Basic Functions
This grouping of "Safe" functions is used to read various data from the Control Module.
Advanced Functions
These functions are capable of making various "programming" changes to the Control
Module. You should refer to the Factory Repair Manual for your particular car (or to other
documented procedures) before "playing" with these functions. It is completely possible to
render your vehicle inoperable or damage components if you make changes in this section
without the correct information and training.
It is normal for some buttons to be grayed out on some control modules. This is an
indication that the control module in question doesn't support those functions. Each of the
function buttons is detailed on the following pages.
Use [Close Controller, Go Back - 06] to properly close the communications session and
return to the Select Control Module screen.
VCDS - Fault Codes - Section 6-A
(VAG 1551/1552 functions 02 and 05)
On this screen, VCDS shows you any DTCs (“Diagnostic Trouble Codes” or Fault Codes)
present in the control module in which a communications session is currently active. VCDS
shows the DTC numbers and also decodes each DTC into meaningful text.
At the top of the screen is shown the VAG Number and Component number as found on
the Open Controller screen.
VCDS tells you how many fault codes have been found and displays each of them. The
5,6, or 7-digit number is a standardized VAG fault code, which can be searched in the
Factory Repair Manuals. The text is a description of the part and failure mode. The letter
and number combination in parentheses is the DIN Component Identifier. This is followed
by elaborators describing the condition of the fault such as “004” meaning “No
Signal/Communication”. The second line contains the P-code, or generic OBD-II code (if it
exists, there are thousands of VAG codes without generic OBD-II equivalents).
The Use Aggressive Mode checkbox applies only to UDS/ODX modules and is checked
by default. When checked, VCDS will retrieve more faults than even the factory VAS tools
in some cases. Uncheck this if you wish to correlate VCDS results with results from a VAS
used in manual (non-guided functions) mode. The AutoScan function always uses
Aggressive Mode.
Fault Codes cont. - Section 6-B
The Display Freeze Frame Data checkbox adds Freeze Frame data for Fault Codes on
control modules using the KWP-2000 / CAN / UDS protocols. Keep in mind that many
control modules are not aware of the actual date and time, so they may display bogus
dates, just as they do with the factory scan tools. Note: Not all control modules fully
support this. As a rule of thumb, cars which were re-designed after 2003 will likely have
some control modules that support it, and older designs will not. There's no harm in leaving
this enabled in any case. However, un-checking it can make the results less cluttered in a
scan which contains many fault codes. In vehicles that do not support Freeze Frame, that
checkbox will not be present.
One component of Freeze Frame data is the Fault Priority number as described below:
Number
Meaning
0
Undefined by the manufacturer.
1
The fault has a strong influence on drivability, immediate stop is required.
2
The fault requires an immediate service appointment.
3
The fault doesn't require an immediate service appointment, but it should be
corrected with the next service appointment.
4
The fault recommends an action to be taken, otherwise drivability might be
affected.
5
The fault has no influence on drivability.
6
The fault has a long term influence on drivability.
7
The fault has an influence on the comfort functions, but doesn't influence the
car’s drivability.
8
General Note
Fault Frequency shows how many times the conditions that caused the fault have
recurred, during all driving cycles. So, if you have a fault with a Frequency of 11, then
conditions sufficient to trigger the fault have happened 11 times since the fault was stored.
The counter can have values from 0 to 254. It is incremented with each occurrence of the
fault (during all driving cycles).
The Reset counter is a number that has been pre-assigned to each fault, with the number
of problem-free driving cycles before the fault presumably clears itself. Each time a driving
cycle occurs, and the conditions sufficient to trigger the fault do NOT occur, then the reset
counter should go down by one. So if you have a fault with a Reset Counter of 40, if the
controller goes through a problem-free driving cycle then that number should go down to
39.
Fault Codes cont. - Section 6-C
[Print Codes] will print a Fault Code Report. If your PC is not connected to a printer when
this button is pressed, be sure to use Windows to set the printer to "Work Off-Line" first!
Later, when you connect the PC to a printer, un-check "Work Off-Line" to print the report.
[Copy Codes] will copy your fault codes to Windows Clipboard. Once you have pressed
the Copy Codes button, you may paste the results into the application of your choice, such
as MS Word or Notepad.
[Save Codes] will save a plain-text Fault Code Report to the Logs directory of your PC,
typically: C:\ross-tech\vcds\Logs\
[Clear Codes - 05] will send a message to the controller asking it to erase the DTCs from
its memory. Some faults cannot be cleared (such as internal processor faults) and the
control module may explicitly refuse or may just still display the fault after a clearing
attempt. Be aware, clicking on Clear Codes does not fix the problem that caused the
fault! DTCs should only be erased after correcting the condition(s) that caused them in the
first place. Note: There is no way to erase individual DTCs while leaving others alone.
This is not a limitation in VCDS. It's just the way the VAG protocols work. Note: In some
cases, the ignition must be cycled after clearing codes but before performing certain
functions such as Basic Settings.
[Done, Go Back] takes you back to the Controller Information Screen where you can
select other functions.
VCDS - Measuring Blocks - Section 7-A
On this screen, you can read all sorts of data from the Control Module in real-time.
Use [Up] and [Dn] to scroll through the available groups (000 - 255 on most Control
Modules) and you can view up to three groups at the same time. Don't become
discouraged when you find some that say "ERROR: Group xxx Not Available" or if you find
some groups where the fields are all blank. Most 1996 and newer ECU's have Groups in
the 200 range, but there are often "gaps" in the numbers.
You can also type a Group number into any or all of the Group boxes and click [Go!]
Dual ECU's: For vehicles with dual ECU's (like the Audi R8), data from both ECU's can be
viewed simultaneously by accessing [31-Engine Other] as shown here:
Measuring Blocks cont. - Section 7-B
You can [Log] the data from the measuring blocks. For more information see Data Logging
(Section 8 of this manual).
[Switch to Basic Settings] can be used to go to Basic Settings for the Group that is
currently being displayed. This should be done only under guidance from the Service
Manual or when following some other documented procedure. For more information, see
the Basic Settings function (Section 17 of this manual).
Note: Multiple Groups are not permitted in Basic Settings. The [Switch To Basic
Settings] button is intentionally disabled if you have groups "running" in the second and
third rows. To stop a running group, click on the box that displays the group number (as
though you wanted to enter a new number). The button is also disabled on controllers using
KWP-2000/CAN/UDS. On those, you need to go directly to the Basic Settings screen.
The data presented in each Measuring Block Group varies greatly from Control Module to
Control Module and between different models and years. Some groups are documented in
the Factory Repair Manuals, but many are not. Feel free to explore the Control Modules in
your car by scrolling through all the Groups. You can't hurt anything with the Measuring
Blocks function!
VCDS will attempt to "scale" the raw data coming from the Control Module into realworld units like degrees C, km/h, etc. At the present time, all scaling conversions are to
metric units.
Note: Group 000 and any other group that displays 10 fields instead of 4 is an exception.
No scaling is possible because the Control Module provides no "Data Type" information for
these. Groups of this type can only be displayed in the top row of the screen.
VCDS also tries to elaborate as much as possible what the data means. Unfortunately, the
"Data Type" information coming from the Control Module is not that precise. For example:
VCDS can tell that a particular field contains a Temperature, but the data from the
Controller doesn't tell us whether this is the Coolant Temperature or the Intake Air
Temperature.
To reduce the confusion, VCDS supports Label Files and will display the name of the Label
File on the top left corner of the screen. If you click on the name of the Label File, the file
will open in Notepad or whatever program you have set to handle *.LBL files. The newer
encrypted *.CLB files cannot be opened in the same manner. When a Label file for the
Control Module you are looking at does not exist, VCDS will come up with an "educated
guess" for what a particular Data Type means. The dealers' VAG-1551 and 1552 scantools do not provide any elaboration; they only show what’s in the display fields!
Group 000 supports special Labels. Due to space constraints on the screen, these labels
are displayed in a "balloon" when the user clicks on a field:
Measuring Blocks cont. - Section 7-C
Label Files also allow a third label field to be defined for each of the normal measuring
block fields. This label is displayed in a balloon when the user clicks on the field. The idea
is to put "specified values" in this field:
Sample Rate: Some ECUs may not be willing to produce more than about 3.5 samples per
second when running a single group, even with the most aggressive protocoltiming settings. Other ECUs may be much faster. Except on the slowest most ancient
PCs, this is a limitation inherent in the firmware in the ECU, not a limitation in the VCDS
software or the PC. Naturally, if two groups are being displayed simultaneously, the
sample rate drops about half what it was running a single group, and 3 groups
simultaneously runs at around 1/3. Sample Rate will vary from controller to controller.
Some controllers (particularly AG4 transmissions and Digifant-III ECU's) use a "hybrid"
data-type that requires reading a long header when changing group numbers. Viewing
multiple groups still works with these data types, but the sample rate becomes extremely
slow. If you see "Reading Header" all the time under the Sample Rate display, you'll know
you've got one of these.
In Engine controllers using KWP-2000 or CAN, there is a [Turbo] button in the top right of
the Measuring Blocks screen when using a HEX Interface. Pressing this button can
significantly speed up sampling, for example over 30 samples per second when logging a
single group in our Touareg. Once you have pressed [Turbo] you will remain in this HighSpeed mode until you exit the Measuring Blocks screen:
The [Graph] button is used to open up VC-Scope, a plug-in for VCDS that allows you to
graph Measuring Group Information. See Section 32 for information on VC-Scope.
Use [Done, Go Back] to return to the Open Controller screen.
Measuring Blocks cont. - Section 7-D
If you'd like to record just a snapshot in time of the current readings in each group, click on
[Add to Log]. This will save the results to your PC, typically in your VCDS\Logs directory
Acceleration Measurement
When you have one or more measuring group with speed (km/h) in it, clicking on
[Acceleration] will bring up the Acceleration Measurement window, which allows you to
enter start and stop speeds and distances. This is described in the Acceleration
Measurement (Section 14 of this manual).
Advanced Measuring Values
You may also want to try the Advanced Measuring Values function (see section 13), which
frees you from the grouping format of the Measuring Blocks function. For controllers using
the UDS/ODX/ASAM protocol, the Measuring Blocks function is not available and you
MUST use Advanced Measuring Values instead.
Warning! If you wish to observe real-time data while driving the car, please use a second
person! Let one drive while the other observes the data, making sure the person holding
the PC is not in front of an active airbag!
.
VCDS - Data Logging - Section 8-A
You can log the data from the Measuring Blocks screen to a .CSV file. These files can be
opened and analyzed with Excel or other spreadsheet applications or played back using
VC-Scope (see Section 32 of this manual).
Export RPM Only when checked will record only RPM from the first field and will not
record other fields. Also, this will only record RPM values that are non-zero. This feature
can be useful if you are logging to output the file to a spreadsheet or other third party
software
While the Log Dialog is open, [Start], [Stop], and [Resume] can all be done with the same
button. [Start] begins saving the data to a log file.
[Stop] discontinues the saving of data to a log file
[Resume] continues the saving of data to a log file.
Data Logging cont. - Section 8-B
Dual ECU's: For vehicles with dual ECU's (like the Audi R8), data from both ECU's can be
logged simultaneously by accessing [31 – Engine Other] as shown here:
The [Marker] button places a sequential number in the file when you click it. This can be
helpful for data analysis.
The [Browse] button allows you to specify the location for your logs. By default, Log Files
will be placed in the Logs sub-folder in your PC, typically: C:\ross-tech\vcds\Logs\
By default, the name of the log file will be the controller number followed by each group
number that you are logging. The name can be changed to anything you'd like. If you reuse an existing filename, your new data will be appended to that file.
Switch to Basic Settings is not currently available while logging (but may be added later).
However, you can start a log while you're in Basic Settings. If VCDS keeps insisting that it
can't open a Log file, you're probably missing the LOGS folder and should re-install VCDS.
Data Logging cont. - Section 8-C
Example using Microsoft Excel:
1. Choose the group or groups that you want to view.
2. Click the [Log] button
3. Use default file name if desired. It will append the old file if you use a particular name
more than once.
4. Click [Start]
5. Drive the car through the tests that you want to perform
6. Click [Stop]
7. Click [Done] when you're finished logging data.
8. Open Microsoft Excel
9. Click File->Open (change filetype to all *.*)
10. Locate the *.csv file that you created, typically in C:\ross-tech\vcds\Logs\
11. With mouse select the columns you want to graph.
12. Click the Chart Wizard button.
13. Select XY (Scatter) and click one of the formats that has lines.
14. The chart wizard will prompt you to name axes if you want.
15. Pick, for example, RPM values for the x-axis and IAT for the y-axis
You can also use the [Graph] button to open the VC-Scope plug-in for VCDS that allows
you to replay LOG files. See Section 32 for information on VC-Scope.
Warning!
If you're going to use VCDS while you're driving, please use a second person! Let one
drive while the other observes the data, making sure the person holding the PC is not in
front of an active airbag! Obviously, do not break any laws, speeding or otherwise while
using VCDS!
VCDS - Single Reading- Section 9-A
This function allows you to look at real-time data from control modules that support it.
However, the data stream coming from the control module gives NO CLUE what the data
means or how to scale it into real-world values.
The only way to know what the values mean is to find a reference to this function in
the Factory Repair Manual for your car.
This function is rare, but it is used, for example, with some OBD-I 2.8L 12V V6 engines.
The very name of this function annoyed us, so we added a twist. You can look at two
channels of "Single Readings" at once!
Use [Up] and [Dn] to scroll through the available groups (000 - 255 on some Control
Modules). Don't become discouraged when you find some where the fields are all blank.
You can also type a Channel number into the Channel box and click [Go!]
Note: On the Open Controller screen, the Supported Codes button will appear in place of
the Single Reading function in modules that support it, since the two functions are mutually
exclusive.
VCDS – Supported Codes- Section 10-A
Supported Codes function: Only some KWP2000/CAN/UDS control modules support
this function and there is no way to tell which have this capability without trying the function.
VCDS can show all DTC and Failure Mode combinations which a control module is capable
of detecting, including the current status of each.
You can sort the results by selecting the radio buttons on the right side of the screen.
Use [OK] to return to the Controller Info / Select Function screen.
Note: On the Open Controller screen, the Supported Codes button will appear in place of
the Single Reading function in modules that support it, since the two functions are mutually
exclusive.
VCDS - View Readiness - Section 11-A
The Readiness Code is a set of 8 bits, each of which corresponds to one monitored
emissions "system" in an OBD-II car. When all readiness bits show "Passed", it means that
all systems have been checked and have passed the on-board tests. The Readiness
screen shows the name of the script in the title bar and under the [Set Readiness] button,
or gives a reason why [Set Readiness] is disabled when that is the case.
Whenever you clear DTCs, all readiness bits that are testable will be set to "Fail" or "Failed
or Incomplete". Most cars do not have all 8 systems, so the ECU should recognize the bits
corresponding to systems that are not actually in the car. These will come up "Passed"
automatically without going through any tests.
It takes a variety of specific driving conditions to "test" all the systems. In practice, driving a
properly-functioning car for 2-3 days including at least one short highway trip, should be
sufficient to test each of the Readiness Bits to set all of the testable ones to "Passed". It
can be done in a short time using a very specific and complicated procedure found in
the On Board Diagnostic section of the Factory Repair Manual for your engine or you can
use the Guided Readiness Script function in VCDS as described later in this section.
View Readiness cont. - Section 11-B
VCDS also decodes Readiness bits into meaningful data on modern TDI engines including
US-market Common-Rail TDI-140 engines. Diesel Readiness is a VCDS exclusive, not
even the VAS-5051/5052 does this:
Click on [Save] to store the results to your PC, typically in this directory on your PC:
C:\Ross-Tech\VCDS\Logs
Use [Go Back] to return to the Open Controller screen.
Notes:
The Readiness function is only available on Engine Controllers that are OBD-II compliant
(all 1996 and newer US-Model) or EOBD compliant (all 2001 and newer European-market
models).
Non-US models and older TDIs may not support the Readiness function even though they
are otherwise OBD-II compliant. OBD-I did not require any "monitors".
12V 2.8L V6 engines may have readiness bits stored in or near Measuring Block
Group 029.
View Readiness cont. - Section 11-C
The Guided Readiness Scripts function will guide the user through the process of setting
Readiness on those engines which support it by clicking on the [Set Readiness] button.
The button will be grayed out if Readiness bits are already set (you can clear fault codes to
un-set them) or if appropriate documentation does not exist in VCDS for that specific ECU:
Guided Readiness Scripts require supporting data in Label files. Not every possible
engine is currently documented but we hope to have most US-model engines covered in
the near future. If you have a specific engine you would like to see covered and have a
written procedure for it, please contact us at [email protected] preferably by
emailing an AutoScan.
Use [Next] to advance through the on-screen prompts or [Cancel] to exit out of Guided
Readiness.
VCDS - Advanced Identification - Section 12-A
(VAS 5051/5052 “Identification Services”)
Corresponds to VAS-5051/5051 "Identification Services"
This function displays additional (and sometimes quite arcane) identifying data from the
control module which does not fit on the Open Controller screen.
Notes:


The Advanced ID function is not available on control modules using the old KW1281 protocol.
The amount of data appearing on this screen will vary based on what the control
module supports.
[Copy] will copy the information shown on this screen to the Windows Clipboard. Once you
have pressed the Copy Codes button, you may paste the results into the application of your
choice, such as MS Word or Notepad.
[Save] will save a plain-text report to your PC, typically in this directory: C:\RossTech\VCDS\Logs
Use [Go Back] to return to the Open Controller screen.
VCDS - Advanced Measuring Values - Section 13-A
This function expands on the Measuring Blocks function and lets you select up to 12
measuring values from as many as 12 different groups from a selection dialog that shows
the contents of the measuring values. This function is available only when a label file exists
for the control module being accessed. For controllers using the UDS/ODX/ASAM protocol,
the Measuring Blocks function is not available and you MUST use Advanced Measuring
Blocks instead. For UDS controllers, the “Group UDS requests” checkbox can speed up
sample rates.
Warning!
If you wish to observe real-time data while
driving the car, please use a second
person! Let one drive while the other
observes the data, making sure the person
holding the PC is not in front of an active
airbag!
Note: You may also want to try the
Measuring Blocks function, which accesses
the same data but in a different format.
(see Section 7 of this manual).
The Advanced Measuring Values function
has two screens, the main one shown
above and the Item Selection Window
shown to the right. Check each value you
would like to show and uncheck each that
you would like to remove. ►
Advanced Measuring Values cont. - Section 13-B
VCDS lets you save a list of Advanced Measuring Values, to be easily accessed later on.
For instance, if you often log Vehicle Speed, Engine Speed, Intake Air Mass, and Ignition
timing, then you can create a file to quickly load those selections again. To save a set of
items, click on the VCDS logo found on the top left corner of the item selection window, and
then select "Save selection to file":
Give the file a name and specify the directory if desired. To load a set of previously saved
items, click on the VCDS logo found on the top left corner of the item selection window,
then select "Load selection from file". Locate the previously saved file and click [Open].
Sample Rate: The amount of data acquired in a given amount of time is determined by the
controller in the vehicle. Selecting a greater number of different Groups will result in slower
sampling so momentary "spikes" or "dips" will be harder to capture. In Engine controllers
using KWP-2000/CAN/UDS, there is a [Turbo] button to significantly speed up sampling,
for example over 30 samples per second when logging a single group in our Touareg. The
controller will remain in this High-Speed mode until you exit the Advanced Measuring
Blocks screen. This function is only available when using a HEX Interface.
[Graph] will open up VC-Scope a plug-in for VCDS that allows you to graph Measuring
Group Information and display customizable virtual gauges. For more information, see the
VC-Scope section of this manual (section 32).
You can [Log] the data from the Advanced Measuring Blocks screen. For more information
see the Data Logging section of this manual (section 8).
[Save]. This will save the results to your PC, typically in your VCDS\Logs directory
When you have one or more measuring group with speed (km/h) in it, clicking on
[Acceleration] will bring up the Acceleration Measurement window, which allows you to
enter start and stop speeds and distances. This is described in the Acceleration
Measurement section of this manual (section 14).
Use [Done, Go Back] to return to the Controller Information screen.
VCDS – Acceleration Measurement - Section 14-A
When you have one or more Measuring Blocks or Advanced Measuring Values with speed
(km/h) in it, clicking on [Acceleration] will bring up the Acceleration Measurement window,
which allows you to enter start and stop speeds and distances. After entering the values
you want to measure, click [Start]. Next, do your acceleration runs in a safe and legal
location. The "clock" will start counting when the car starts to accelerate. When complete,
click on [Save] to save a copy of your results to your C:\Ross-Tech\VCDS\Logs directory.
Use [Done, Go Back] to return to the Measuring Blocks or Advanced Measuring Values
screen.
Note: The +/- tolerance shown is based on the sample rate of the data selected. Use a
single measuring group and check the Options screen for tips on obtaining the fastest
possible sample rate. Our testing at a dragstrip yielded results within the tolerance.
Obviously, changes like overall tire diameter can greatly affect the results.
Warning!
If you wish to observe real-time data while driving the car, please use a second person!
Let one drive while the other observes the data, making sure the person holding the PC is
not in front of an active airbag!
VCDS - Login - Section 15-A
The Login Function must be used on some (but not all) Control Modules before you can
Recode or change Adaptation values. On others, it "enables" certain features like cruise
control. Valid Login codes can be found in the Factory Repair Manual for your car.
If you are working on an Immobilizer, select [Use 7-digit PIN/SKC] to enter a 7-digit Secret
Key Code. This function is described in Section 16.
Balloons: VCDS can show Login "charts" when appropriate information is available in a
Label File for the control module in question. The balloon will appear after a few seconds if
the Label File contains the appropriate information.
This warning appears in the upper
right corner of the screen if a
session is disconnected after you
have done a Login. ►
The most common cause of this is the use of an incorrect login code or a 7-digit PIN/SKC
based on an incorrect Immobilizer ID or incorrect data entered in the 7-digit dialog. You will
need to exit the Controller and do another Login.
Use the [Do It!] button to save the Login and return to the Select Function Screen.
Use the [Cancel] button to cancel the Login and return to the Select Function Screen.
VCDS - 7-digit PIN/SKC - Section 16-A
The 7-digit PIN/SKC (Secret Key Code) dialog is used for Key Matching and Immobilizer
Adaptation. This function is still in VCDS but is pretty much obsolete since VW/Audi
stopped giving out 7-digit SKC's in 2005. Just in case you got your 7-digit SKC before then
(along with the necessary WSC, Importer and date the code was generated), instructions
on using this function can be found on our website:
http://ross-tech.com/vcds-lite/manual/pinskc.html
Important: Unless you ALREADY have the SKC information for your vehicle and
components then you will NOT be able to do any of the Immobilizer functions. Please
see the FAQ number 4.15 for information on SKC availability.
VCDS - Basic Settings - Section 17-A
Basic Settings mode is very similar to Measuring Blocks and the contents of each display
group is the same. The difference between the functions is that the Control Module may try
to perform various calibrations while in Basic Settings mode.
The most common use for the Basic Settings function is to recalibrate the Throttle Body.
Another common use for Basic Settings is to bleed the ABS Hydraulic Unit on newer cars.
Please refer to a Factory Repair Manual for your car before attempting to do these
procedures!
In controllers using KW-1281, the Basic Settings function “does its thing” as soon as you
have entered a group number and clicked [Go!] or as soon as you have entered Basic
Settings through the Measuring Blocks function. In Controllers using KWP-2000/CAN/UDS,
there may be an [ON/OFF/Next] button that allows you to initiate and exit Basic Settings
while still being able to see the values in the measuring groups. This does not appear every
time and its appearance and function are up to each controller in the car.
[Add to Log]. This will save the results to your PC, typically in your VCDS\Logs directory
[Switch to Meas. Blocks] will switch back to the passive (and "safe") Measuring Blocks
mode (only in controllers using KW-1281).
[Graph] will open up VC-Scope a plug-in for VCDS that allows you to graph Basic Settings
Information and display customizable virtual gauges. For more information, see the VCScope section of this manual (section 32).
Basic Settings cont. - Section 17-B
You can begin and end a Data [Log] while in Basic Settings. See section 8 of this manual
for information on Data Logging.
For control modules that have a Label File with Basic Settings information, a drop-down
menu is available which allows you to select from the supported Basic Settings functions.
Below that menu is an area to display additional info for Basic Settings. The data to be
displayed in this area comes from the Label files and it may take some time before tips are
included for most Basic Settings groups.
As is the case for other functions under UDS, there are no longer any channel or group
numbers. Instead, the Basic Setting to be performed must be selected from a drop-down
list:
Dual ECU's: For vehicles with dual ECU's (like the Audi R8), the Basic Settings mode for
both ECU's can be accessed simultaneously by addressing [31 – Engine Other]
Warnings:

You should refer to the Factory Repair Manual for your particular car (or some
other documented procedure) before "playing" with the Basic Settings function.
Failure to follow the proper procedures can result in serious damage to the
vehicle.

Although you can use the [Up] and [Dn] buttons to scroll through the available
groups just like on the Measuring Blocks screen, this is NOT a good idea since
you may put the Controller into Basic Settings for a Group that you did not intend.
Basic Settings cont. - Section 17-C
On UDS control modules that offer "Instructions", VCDS will automatically display them. In
addition, UDS Measuring Values can be displayed simultaneously:
Basic Settings cont. - Section 17-D
Notes:



Multiple Groups are not permitted in Basic Settings. The data presented in each
Basic Settings Group varies greatly from Control Module to Control Module and
between different models and years. Some groups are documented in the
Factory Repair Manuals, but many are not.
VCDS tries to elaborate on the meaning of the data as much as possible but the
"Data Type" information coming from the Control Module is not very precise.
For example: VCDS can tell that a particular field contains a Temperature, but
the data from the Controller doesn't tell us whether this is the Coolant
Temperature or the Intake Air Temperature.
To reduce the confusion, VCDS supports Label Files and will display the name of
the Label File. The Label File name is displayed on the top left when you are in
Measuring Blocks or Basic Settings. If you click on the name of the Label File,
the file will open in Notepad or whatever program you have set to handle *LBL
files. When a Label file for the Control Module you are looking at does not exist,
VCDS will come up with an "educated guess" for what a particular Data Type
means. The dealers' VAG-1551 and 1552 scan-tools do not provide any
elaboration; they only show what’s in the display fields! Basic Setting will display
a popup balloon when the mouse if hovered over each value, if the Label File
contains information for that field in that controller. See section 7 for more
information on the Measuring Blocks function.
VCDS - Output Tests - Section 18-A
The Output Tests function is used to test a Control Module's Electrical Outputs (and
the wiring that connects it to the various devices). Output Tests under
KWP-2000/CAN/UDS includes simultaneous measuring data when available from the
control module in question.
To begin Output Tests, and to progress through each step, click [Start/Next]. In some
cases an [Activate] button will appear, depending on the specifics of the control module.
Notes:
The Outputs that can be tested and the sequence in which they become active are
controlled strictly by the Control Module; this is not a function of the Diagnostic Tester. To
find out which Outputs can be tested and the sequence in which they will become active,
please refer to the Factory Repair Manual for your car.
Once the Test Sequence has been started, clicking [Done, Go Back] will take you back to
the Open Controller Function Screen. THE TEST SEQUENCE WILL STILL BE ACTIVE!
Most Control Modules will permit the Output Test Sequence to be run only one time per
session. If you run the Test Sequence to completion, VCDS will allow you to return to the
previous screen without closing the session, but you may not be able to run the Output Test
Sequence again. If you need to run the Sequence again, manually Close the Controller
and re-start the session. On some cars, you must cycle the key OFF and ON or even start
the engine (to clear the cylinders of fuel).
Some Output Tests require additional action before they become active. Fuel Injectors are
a common example. To activate a Fuel Injector, you must press (and in some cases
release) the gas pedal. Exact details can be found in your Factory Repair Manual.
Output Tests cont. - Section 18-B
On most systems, the Output Tests function is only available when the Engine is not
running.
It is perfectly normal to see a "short to ground" message in the process of running Output
Tests. The ECU identifies which output it is currently testing by sending a fault-code
number. On many ECUs the full text for this fault code includes "short to ground". Why?
Because one side of the actuator in question has 12V on it all the time and the ECU
completes the circuit (and turns the actuator on) by pulling the other side to ground.
Warning:
Do not use the Output Tests function on any system while the car is in motion! Running
Output Tests on the ABS brake system can temporarily disable the brakes entirely and
cause individual wheels to lock and unlock.
We strongly suggest you refer to the Factory Repair Manual for your specific car
before running Output Tests on any Control Module so you will know what to expect!
If you try to perform Output Tests on an Airbag controller, the following warning will pop up:
For example, in the VW Touareg, a specific procedure must be performed to be able to
start the vehicle if Output Tests on the Airbag Controller have been performed.
Output Tests cont. - Section 18-C
Selective Output Tests. On those modules that support it, this is a more sophisticated
version of the traditional (sequential) Output Test function. It allows the user to select a
particular output and activate it directly without going through a pre-defined sequence to get
there. Some modules have outputs which can only be tested this way. Selective Output
Tests requires supporting data in a label file. There is no way to efficiently query a control
module to find out which outputs are supported.
Output Tests cont. - Section 18-D
Measuring Values can be displayed during Output Tests in UDS/ODX modules. This
can be handy to verify that certain outputs are functioning as intended:
VCDS - Recode or Long Coding - Section 19-A
Recode is used to set various options in a Control Module. Note: Some Modules require a
valid Login before you can re-code them.
Warning! You should refer to the Factory Repair Manual for your particular car (or some
other documented procedure) before attempting to Recode a Control Module. At the very
least, write down the original values, saving an AutoScan is a great way to do that. There
is no other way to "undo" the values if what you're trying to do doesn't work out.
VCDS can show coding
"charts" when appropriate
information is available in a
Label File for the control
module in question. This data
is shown in a balloon on the
coding screen. ►
Recode cont. - Section 19-B
A feature unique to VCDS: You can leave the WorkShop Code unchanged, or enter any
workshop code you desire. Certain other programs always leave a tell-tale WSC when you
re-code a module. The Importer Number is only relevant for recoding controllers that use
KWP-2000. By default, this will remain unchanged unless you have set up an Importer
Number in the Options screen.
Airbag Coding:
When coding new Airbag Modules in many VW models, VCDS can "Suggest" an
appropriate Coding value based on the Index number of the airbag controller. This feature
is available only when VCDS is used with one of our Professional Grade (HEX) interfaces.
Disclaimer: We cannot guarantee that the coding which VCDS may suggest will be correct,
but there should be no harm in trying it. If it's not correct, the control module should refuse
to accept it and the coding will remain at 00000. To access this function, click on the
[Coding Helper] button:
Follow the instructions on the screen to locate the index number for the airbag controller:
Recode cont. - Section 19-C
As long as the Index entered is valid and documentation exists in the appropriate label file,
the new Coding (either short coding or Long Coding) should be entered into the Soft
Coding field:
See the Airbag Coding Page for your car on our Website for more info:
www.Ross-Tech.com/vag-com/cars/airbag-coding.html
Coding of Slave Modules. On the latest cars, many "slave" modules are codeable. The
coding screens (both regular and "long") will present a drop-list of available modules which
can be selected for coding:
Recode cont. - Section 19-D
Long Coding. This function is needed to Code some control modules in the newest cars
that use CAN for diagnostics. Due to the complexity of Long Coding strings (up to 255
bytes of hexadecimal data) we've accommodated (and urge) the use of Copy & Paste in
this function and usage of the Long Coding Helper.
Long Coding Helper is used with applications such as Niels Ezerman's excellent
LCode.exe (included with the latest distribution of VCDS). Click on each of the Byte
numbers in row 3) and you'll see the selectable options in row 4). They can be individual
checkboxes as shown below. Check or Un-check the boxes for the desired results.
Example: "Adaptive Cruise Control (ACC) installed".
Recode cont. - Section 19-E
Some coding configurations require multiple bits to be changed. In these cases, you can
select from a drop-down menu that represents the appropriate bits:
After making the desired changes in the Long Coding helper, closing that application (by
using the [ESC] key on your keyboard or by clicking the Windows X box on the top right of
the screen or clicking the Exit button on the top left of the screen) will send your new
Coding value back to the Coding screen where you can click [Do It!].
The Battery Coding Assistant is used for cars that require a replacement battery to be
coded in the 61-Battery Regulation module: Note that the 10 digit serial number may be
preceded by the battery vendor code, for instance VAO for Varta. If the code is
VAO25402160104 then drop the VAO and just enter 25402160104:
Recode cont. - Section 19-F
On some new vehicles like the 8T0 (Audi B8 platform), the Gateway Installation is not
accessible via Long Coding. In such cases, use the [Installation List button in the Open
Controller screen for CAN Gateway to access this screen. This function is available in all
Gateways that support an Installation list:
Use the [Do It!] button to save the new Soft Coding to the controller and return to the Open
Controller Function screen.
Use the [Cancel] button to return to the Open Controller Function screen without saving.
VCDS – Adaptation / Long Adaptation - Section 20-A
The Adaptation function allows you to alter certain values and/or settings in control
modules that support it.
Warning!
You should refer to the Factory Repair Manual for your particular car (or some other
documented procedure) before "playing" with the Adaptation function. However, many
available Adaptation Channels are totally undocumented! You can use the [Up] and [Dn]
buttons next to Channel Number to scroll through all 255 possible channels, or you can
manually enter a channel number and click [Read]. If a channel exists, VCDS will show
you the Stored Value. If a channel does not exist, the Stored Value will show as "N/A".
Other data the controller may or may not send will be decoded and shown in the four
display fields at the top of the screen.
If an Adaptation Error warning appears, indicating that the control module is Uninitialized
you must let VCDS write defaults to the WSC, Importer and Equipment numbers before the
value can be changed. Click [Yes] followed by [Do It!]
Adaptation / Long Adaptation cont. - Section 20-B
Label Files can support values and descriptions for Adaptation channels. A help chart may
be displayed in a balloon. For control modules that have a Label File with Adaptation
information, a drop-down menu may also be available, which allows you to select from the
supported functions:
Once you have reached a channel of interest, you can use the [Up] and [Dn] buttons next
to New Value to incrementally change the value. Or you can directly enter a New Value
and click [Test]. This will tell the controller to temporarily use the new value so you can
evaluate its effects.
When you are satisfied with the effect of a New Value, you can store it in the Controller
permanently by clicking [Save].
[Add to Log]. This will save the results to your PC, typically to your C:\RossTech\VCDS\Logs directory.
Notes:
Channel 00 is a special case. Performing a [Save] to Channel 00 resets all adaptation
values to their original factory defaults. This only works in controllers that support this
function, see your Factory Repair Manual to find out if this procedure applies to each
controller in your vehicle.
Some Engine and Immobilizer controllers will require a valid Login before permitting you to
[Test] or [Save] Adaptation values.
Values put in with [Test] but not Saved will persist until controller is powered-down.
Adaptation / Long Adaptation cont. - Section 20-C
UDS: For controllers using the UDS/ODX/ASAM protocol, the drop-down menu MUST be
used, since traditional Adaptation Channels do not apply. VCDS supports Adaptation for all
control modules in the VW Crafter / LT3 as explained on this page on our website:
http://ross-tech.com/vcds/tour/LT3.html
In Adaptation for UDS controllers, WSC, Importer, and Equipment numbers can be entered
if needed by the controller:
Long Adaptation is a subset of the Adaptation function and is used/needed (for example)
to balance the fuel injectors on Common-Rail TDI engines (such as the BKN). It is also
used for the CAN Gateway of new vehicles like the Audi A5 as shown here:
Click [Done, Go Back] to return to the Open Controller Function Screen.
VCDS - Security Access Screen - Section 21-A
(VAG 1551/2 Function 16, KWP-2000 only)
The Security Access Function must be used on some (but not all) KWP-2000 Control
Modules before you can Recode or change Adaptation values. On others, it "enables"
certain features like cruise control. Valid Login codes can be found in the Factory Repair
Manual for your car.
Balloons: VCDS can show Security Access "charts" when appropriate information is
available in a Label File for the control module in question. The balloon will appear when
the mouse cursor is hovered over the Enter security access key field.
The Security Access Function supports 7-Digit SKCs. This type is largely obsolete since
VW no longer give out PIN/SKC's but has been left in place for those who obtained their
SKC, Importer, WSC, and date prior to 2005.
For more information, see section 16 in this manual for the 7-digit PIN/SKC function.
The Option field is only to be used if you are given specific instructions from Ross-Tech.

VCDS – SRI Reset- Section 22-A
The [SRI Reset] function is used to reset the Service Reminder in vehicles so equipped.
The function will automatically access the Instrument Cluster and will retrieve SRI
instructions from the Label File as well as current values stored in the Cluster. New values
can be entered by hand, or the user can select the drop-down list to choose from a number
of functions which will load standard value sets.
Models using flexible service intervals may show "---" as values for the time/distance to the
next service in the instrument cluster. This is not an error. The system requires a certain
time/distance to calibrate itself to show meaningful values, usually this takes about 300
miles or 500 km.
In many newer Audi models (2008 onward), the default "Simple Service Reset" or "Basic
Service Reset" choice cannot be used. Instead, you must pick the appropriate choice for
your region, for example "#2 Mileage based Service Reset (USA)".
On the latest cars using UDS/ODX diagnostic protocols for the Instrument Cluster, the SRI
Reset function does not apply. Instead, SRI must be reset by saving the appropriate
Adaptation values directly in the Instrument Cluster. Please contact Ross-Tech via email if
you need assistance with this function.
This page contains an example of SRI Reset in a UDS Cluster (in a Mk6 Golf)

SRI Reset cont. - Section 22-B
The [Save to logfile] button can be useful when there are questions about or difficulties
with the SRI function as it's an easy way to send us a snapshot of what's going on. Data is
saved to the Session Log.
Upon clicking [Perform SRI] the new values will be stored in the (often less than intuitive)
sequence required. After cycling the ignition, the cluster should no longer indicate that
service is due.
Note: The Service Reminder Function requires supporting data in Label files. VCDS ships
with a fairly comprehensive set, but we doubt we've managed to cover every possible car.
If you encounter a car that has Service Reminders (not all cars have this) for which the SRI
Reset function is not accessible, please send us a Controller Channels Map of the
Adaptation channels from the Instrument Cluster in that car.

VCDS – Generic OBD2 - Section 23-A
(VAG 1551/1552 Address Word 33)
Generic OBD-II functionality. Because many of VW's recent factory repair manuals no
longer have traditional 01-Engine "On Board Diagnostic" information and have replaced it
with "Generic Scan Tool" data, this has become much more important than it was in the
past. Click each of the Mode buttons to access each OBD-II function.
Generic OBD-II functionality is "Supported" only on VW, Audi, Seat, and Skoda
cars. It will likely work on many other brands of cars. We'd be happy to receive feedback
as to what other brands and models of cars it does and does not work on, however, we do
not feel obligated to make it work on other manufacturer's cars.
Generic OBD-II functionality is limited to cars using ISO 9141-2 ("CARB"), ISO 14230
("KWP-2000") and ISO-15765 ("CAN") protocols. None of our interfaces support the
SAE J1850-VPW and J1850-PWM protocols used by most US-market pre-2008 GM and
Ford products, so VCDS cannot work at all on those cars. Most early (1996-2000) OBD-II
compatible Chrysler cars used the compatible ISO-9141-2 while many 2001-2007 Chrysler
cars use the incompatible SAE-J1850 standard. Most European and Asian cars use ISO
or CAN and should be compatible. Generic OBD-II compatibility was required as of model
year 1996 in the USA, model year 1998 in Canada, and 2001 (gasoline) or 2004 (diesel) for
in the European Market. All 2008 and newer vehicles sold in the US are required to use
CAN-Bus diagnostics for Generic OBD-II so it shouldn't hurt to try this function on any
brand.
Generic OBD2 cont. - Section 23-B
Interfaces: Our HEX+CAN interfaces support ISO 9141-2 ("CARB"), ISO 14230 ("KWP2000") and ISO-15765 ("CAN") protocols. Our non-CAN HEX-, KEY-, and KII- series
interfaces support ISO 9141-2 ("CARB"), ISO 14230 ("KWP-2000"), but do not support
ISO-15765 ("CAN"). Our Micro-CAN interface support ISO-15765 ("CAN"), but do not
support ISO 9141-2 ("CARB") or ISO 14230 ("KWP-2000") for generic OBD-II. The ISO15765 ("CAN") protocol was introduced in a few cars in model year 2004 and became
universally required in all cars sold in the US market for model year 2008.
Each Generic OBD-II mode is defined by SAE J1979 - the specification paper is available
from:
www.sae.org
Below is a brief overview of what each Mode does, refer to a Factory Repair Manual for
specific information and testing steps.
Mode
Meaning
Read Data allows you to view real-time emissions-related sensor and status data
reported by the ECU. The sample rate can be sped up considerably by using the
[Turbo] button and by checking No wait for 2nd controller. Since Generic OBD-2
can request the same information from both the Engine and Auto Trans, it may
cause unnecessary delay for Engine readings if you aren't concerned about data
from the Auto Trans.
1
1-01
Readiness shows the status of each of the emissions systems monitored by the
ECU.
2
Freeze Frame shows the conditions present when an emissions-related fault last
occurred.
3
Current DTCs shows the present emissions-related fault(s). VCDS gives you a
checkbox to convert the code description into VW/Audi-specific ones.
4
Clear DTCs erases the Current and Pending DTCs. It does not repair the condition
that caused them. It will reset Readiness as well, meaning the ECU will have to test
monitored systems again before the corresponding bits read "Pass".
5
O2 Sensors shows the data associated with each O2 sensor, chosen from a dropdown menu.
6
Non cont. tests will run a pre-defined set of tests for various emissions-related
components, for example O2 sensor aging tests.
7
Pending DTCs are fault codes that have been identified by the ECU but are
deemed not yet critical enough to trigger the MIL.
9
Vehicle Info can store information including the VIN, calibration versions, and
tracking information. The quantity of info varies wildly between cars.
10
Permanent DTCs are faults so severe that they cannot be erased with a scan tool,
only by the ECU itself when it has tested and confirmed that the problem has been
repaired.
VC-Scope is able to graph generic OBD-2 Mode 1 data. See the VC-Scope section in
Section 32 for more information.

VCDS - Applications- Section 24-A
The Applications screen contains many handy functions, most of which are described in
individual sections on the following pages.
Check for and erase faults
[Gateway Installation List]
Only available only on Gateways in cars using a direct CAN connection for diagnostics (like
the new A8 and all Golf-5 chassis cars). This very fast function takes about 3 seconds to
query the car's Gateway to find out what modules are installed in the car and what their
status is. Any modules having fault codes should show a "Malfunction" and will be
highlighted in RED. Double-clicking on any of the Control Module names will open that
controller. This function is explained in the AutoScan portion of this manual in Section 3.
[Erase All DTCs]
On vehicles using CAN-Bus for diagnostics, VCDS clears all of the fault codes in all control
modules in the car without accessing all the control modules individually. This function is
explained in the AutoScan portion of this manual in Section 3.
The [eMail today's debug/log files] button will open up your default email client, and will
compose a message to [email protected] with all of the log files and debug files
with the current date.
The [Upload debug/log files] button will open up your default browser to a special page
that allows you upload files and email them to [email protected] even if you do not
have an email client installed.
Use [Done, Go Back] to return to the Main screen.
VCDS – Transport Mode - Section 25-A
Transport Mode
On vehicles using CAN for diagnostics, there is a special Transport Mode that is used by
the factory to put the cars into a "sleep" mode to conserve battery charge during long
periods of inactivity.
[Activate Transport Mode]
Clicking this button will put applicable vehicles into Transport Mode, shutting down most
systems.
[De-activate Transport Mode]
Clicking this button will "wake up" applicable vehicles from Transport Mode, powering up
most systems.
On some early CAN-based cars, Transport Mode cannot be re-enabled once the car has
more than 150km on the odometer.
In the B7 Audi A4, Transport Mode works a little differently since this car doesn’t have a
CAN Gateway. To take the car out of transport mode, go into

VCDS – Controller Channels Map - Section 26-A
[Controller Channels Map]
Rapidly scans through all 255 possible Measuring Block groups or Adaptation Channels on
any controller and writes a "map" file.
Choose the Controller Address (such as 01 for Engine), then any Login or security access
code (not needed in most cases, contact Ross-Tech for assistance), then select either
Measuring Blocks or Adaptation. Output is your choice of .CSV or .PLB / .PLA ("Prototype
Label, Blocks" or "Prototype Label, Adaptation"), which is useful for creating new label files
or taking a "snapshot" of all available data from an ECU.
Click [Go] to begin the process, the results will automatically be saved to your
C:\Ross-Tech\VCDS\Logs directory.

VCDS – EDC-15-16 Mileage Checker - Section 27-A
[EDC-15-16 Mileage] is found in the Applications Screen and is used to show an
independent "odometer" reading stored in the ECU. EDC-15 is found in older TDI engines
like the North American market VE 1.9L Golf/Jetta/etc. EDC-16 is used in 2.0L TDI's
including all North American PD engines, but not in the newest CR engines. This function
also works with some EDC-15 V6 TDI ECUs. This function can be useful as a means of
cross-checking the mileage on a used car before making a purchase, particularly in Europe
where odometer fraud is rampant.
The Option field is only to be used if you are given specific instructions from Ross-Tech.
VCDS - Control Module Finder - Section 28-A
This function cycles through each possible address in the vehicle, finding each controller
and reporting its Address, Name, Protocol, Part Number, Component Number, Soft.
Coding, and WorkShop Code.
Note: No one car has all Modules! Newer cars have more, older cars have fewer
You can scan selected address ranges or use the default starting and ending addresses. If
you check Use CAN Only then the Module Finder will not check for any modules on the Kline.
[Start] begins the finder. Beware; a "full" scan can take 45 minutes or more. Of course, you
can scan selected address ranges.
[Stop] stops the finder.

If you close the Auto Scan dialog, any data in its output box will be lost. If you would like to
keep a record, click the [Copy] button first, then you can then paste the results into the
application of your choice, such as MS Word or Notepad.

typically in C:\ross-tech\vcds\Logs\
[Clear] This erases your results.
To return to the Applications Screen, click [Close]
VCDS – Optical Bus Diagnostics - Section 29-A
The [Optical Bus Diagnostics] function found in the Applications Screen is used on
models with a MOST bus to narrow down the location of a break in the network. Many
control modules will be completely inaccessible via conventional diagnostics if there's a
break in the MOST bus.
The above example shows a 4F Audi A6 with a break in the MOST bus. In this case, it's
clear that the modules are all electrically OK, but the Optical bus is broken between the
Sound System module and the Voice Control module.
You may change the Diagnostic Type from "Standard" to "3dB Attenuation" if your results
are not conclusive. The attenuation means all modules are sending with less output
(initiated by the MOST master), but the individual MOST participating control modules can
attenuate individually to check if individual modules are responsible for problems.
VW/Audi sells a handy loop of fiber (part number 4E0 973 802 ) that can be used in place
of each of the components in the system. This can be used to check whether a component
is responsible for breaking the loop.
Click on [Start] to begin checking the controllers on the bus.
[Copy] will copy the results to Windows Clipboard. Once you have pressed the Copy
Codes button, you may paste the results into the application of your choice, such as MS
Word or Notepad.
[Save] will save a plain-text report to your PC, typically in this directory: C:\RossTech\VCDS\Logs
VCDS – Options Screen – Section 30-A
On this screen you can set a number of Options organized by tabbed sections that must be
used the first time you run VCDS on a PC.
Options Screen cont. – Section 30-B
Port and Protocol Options
Select Port
Set the COM Port to which you have connected the Interface Adapter. Serial Ports should
be assigned to COM1 through COM4 (most often COM1 by default) while USB has only its
eponymous choice. Make sure the ignition is turned on and the interface plugged into the
vehicle, then click [Test] to see if VCDS can find the interface. See Getting Started (section
1 in this manual) for more information.
The [LEDs] button causes the LED on the Interface to blink and may be useful for testing a
port's outputs for troubleshooting certain connection issues.
Protocol Options




Start Baud is the first baud rate that VCDS will try when connecting to a
controller. The current default value is 0. This means VCDS will determine the
correct start baud on its own. With our current Interfaces, this field is unavailable.
KW2 Delay has to do with the amount of time used during the initialization of a
session between the PC and the car. The current default value is 30. Do not
change this value from the default unless you are having difficulties
communicating with a particular controller. Contact us for advice if you are.
TST Addr. has to do with the packet addresses used by KWP-2000. The current
default value is -1. Do not change this value from the default unless you are
having difficulties communicating with a particular controller. Contact us for
advice if you are.
Debug Level controls how much debugging information VCDS records. A zero in
this field (the default) means NO debug output will be generated whatsoever.
This should decrease VCDS's susceptibility to interference by things like virus
scanners (except when logging data). There should be no reason to set Debug to
anything other than zero unless you are instructed to do so by Ross-Tech.
Options Screen cont. – Section 30-C
Protocol Options cont.




Blk Int affects the protocol timing. The current default value is 55. To get the
highest sample rate possible in the Measuring Blocks screen, set this to 25.
Note, however, that this may cause unreliable communications with some
controllers.
Char lnt also affects the protocol timing. The current default value is 1. To get
the highest sample rate possible in the Measuring Blocks screen, set this to 0.
Note, however, that this may cause unreliable communications with some
controllers.
KP2 Time only applies to controllers using the KWP-2000 protocol. The current
default value is 25. Decreasing it increases the sample rate in Measuring Blocks
on control modules that use the KWP-2000 protocols. The default value should
work for all applications, but if it does not, you can always increase it again (to a
maximum of 99).
CAN Timeout defines how much longer than normal VCDS is going to wait for
the module to respond to a given message. Do not change this value from the
default value of zero unless you are having difficulties communicating with
a particular controller. Contact us for advice if you are.
Init Parameters

Bypass OBD-II Fastinit should only be checked if you are experiencing difficulty
connecting to a vehicle using generic OBD-II.

Force K on Engine is used on Engine controllers that have a choice of using
CAN-Bus or k-line for diagnostics, such as the Mk5 Jetta 2.5l. This feature can
be useful since the K-line often delivers faster sample rates while datalogging
than does the CAN-Bus on modules that support both. Since some modules talk
only via CAN, this box is unchecked by default.

Bypass CAN Init should only be checked if you do not want VCDS to try
connecting to vehicles using the CAN-Bus

Boot in intelligent mode is checked by default. It allows VCDS to quickly
determine baud rates when using a HEX interface. If you wish to try using your
Ross-Tech dongle interface with 3rd party software (which is not supported by
Ross-Tech), you may want to run a Test, then uncheck Boot in intelligent
mode then run another Test. This will cause the interface to behave like an older
style dumb interface and will not be compatible with most 6J Ibizas and it will be
noticeable slower building the list of installed modules on the Select Control
Module screen.
Reduce CPU Usage checkboxes will greatly increase responsiveness of other apps
running at the same time as VCDS. The disadvantage is a somewhat reduced sample
rate.


KWP-1281: The default state for this box is unchecked. This reduces
CPU usage when connected to controllers using KWP-1281. Using this
feature *may* make the session with some control modules unreliable.
KWP-2000: The default state for this box is unchecked. This reduces
CPU usage when connected to controllers using KWP-2000.
Options Screen cont. – Section 30-D
[Restore Defaults] will reset all Protocol Options (except WorkShop Code and VZ/Importer
number) to their "as-delivered" settings.
If you right-click on the VCDS icon on the top left of the VCDS screen, you can select
“Delete config file and close”. This can be very handy, especially if you have made the
window size too large.
User Interface and Identification
Workshop Identification
Some control modules do not allow themselves to be Coded with the zero values for
WSC, Shop, and Importer. VCDS should prompt you with a message to input nonzero values in such cases. You should NOT make such changes in the Options
screen itself.


Shop Name is displayed on reports, such as the Fault Code Report.
The WorkShop Code (known as the WSC) is found on the
Admin screen of a dealer's VAS-5051, as well as on the
dealer's stamp. The default value is 00000. For example,
using the stamp shown at the right, the dealer's number is
401/742. To derive the WorkShop Code, drop the first digit
and use the remaining digits in order. In this example,
Evergreen Terrace Volkswagen has a WSC of 01742. This
only applies to US VW dealers. Canadian dealerships use
a 4-digit number on their stamp. To find the WSC, place a
9 before their number. ►
Note: If you are an individual user or independent mechanic, just leave the WorkShop Code
and VZ/Importer number set to "00000" and “000” respectively. This allows VCDS to
operate in “stealth” mode, keeping whatever WSC and VZ that was already in the
controller. If you are using VCDS at a Dealership, enter your Dealer's Workshop Code and
VZ. The Work Shop Code and VZ are not easily changed once set on this screen. Contact
us for advice if you need to do so.


The VZ/Importer number is essentially a "region code" extension to the Work
Shop Code (should be 444 for US, 999 for Canada). The default value is 000.
The Equipment Number field is used most often when coding new control
modules. The default value is 00000.
User Interface


Left Margin Printing This is the number of spaces that printed pages are shifted
to the right.
Window Size This function allows you to change the apparent size of the VCDS
window on your screen. Adjust this in small increments since it is possible to
make VCDS so large that it is much bigger than your screen! To see the resizing
take effect, click Save, then close VCDS. When you restart, the new window size
should be shown.
Options Screen cont. – Section 30-E
User Interface and Identification cont.


Disable Sounds Checking this box will prevent VCDS from making sounds when
an operation is complete, for example at the end of an AutoScan or at the end of
Acceleration Measurements. This will not prevent Windows sounds when an
error message pops up.
Build list of CAN controllers prior to selection dialog This box is checked by
default. In CAN based cars that have a proper Gateway supporting an Installation
List, VCDS will automatically populate one or more Installed tabs containing
buttons for only those control modules that are actually installed in the car. It
does take about 1.5 seconds to get the list from the Gateway, so a bit of a delay
when clicking [Select] is normal/expected. Customers who use VCDS primarily
on older cars which do not have an Installation List available may want to
uncheck this box.
Check for Free updates
If an internet connection is available, VCDS will notify the user when updates are
available and will ask permission to download and install updates. Because we
do not want to burden customers' PCs with a resource hogging update
scheduler, VCDS will only check for updates when it is started and when the PC
is rebooted. We've tried to make this as unobtrusive as possible -- VCDS will
not complain if there's no internet connection available -- you just won't get
updates.
Select from the drop-down menu to determine if, and when VCDS should
automatically check for updates when the program starts. You can also click the
[Check for updates now] button to manually initiate a check.
Note: Some 3rd-party firewall software may complain that VCDS is trying to
access the internet -- if this happens you should either tell the firewall to allow it,
or turn off Automatic Updates.
[Save] causes the current options to be stored. Note that until you have Saved your
preferences, all buttons on the VCDS Main Screen will be grayed-out except Options.
[Apply] lets you use and test the options without storing them. The next time you restart
VCDS, the options previously stored will be used.
[Cancel] takes you back to the Main Screen without any effect.

you have connected to a car and checked fault codes in a controller. After you
have done this, you will have a Serial Number composed of letters and numbers..

License Status should always be Fully Registered / Activated, with all of our
Current Interfaces since they store their own activation. If it says Not Tested,
then you will need to connect to a controller (like 01-Engine) and for example
check Fault Codes. Afterward, the Serial Number should be visible.

TDI Timing Checker ’Plug-In’ for VCDS - Section 33-A
The TDI Timing Checker is automatically installed when you install VCDS.
Note: This ONLY applies to VE Engines and DOES NOT
apply to PD (unit injectors) or CR (common Rail) engines
This plug-in allows you to check the injection timing setting on a VE TDI engine (NOT PD or
CR varieties). This needs to be done after you change the timing belt and should be done
every once in a while to keep tabs on belt stretch and pump/pulley misalignment. The
standard procedure for this is to have the engine idling at operating temperature (coolant
temp >85*C), go to measuring block 000 for the engine, switch to basic settings and report
fields #2 (injection timing) and #9 (fuel temperature) on a special graph.
This plug-in reports the timing on the graph in real-time, so you don't need to have your
manual sitting on your lap at the same time. The application also gives you a comment in
the "result" field, that will tell you if all the conditions are fulfilled to check the timing (some
people don't realize you need to have the engine running, for instance...) and if your timing
is within spec or not.
The history of the last 100 samples is displayed as a "cloud" of points. From the size and
shape of this "cloud" you can see how much "jumping around" your engine is doing, and
your average timing is probably right in the middle of the cloud.

The TDI Timing Checker works only as a “plug-in”. You must start it using the [TDI Timing]
button in VCDS. Starting it any other way will result in error messages and it won’t work.
Note to PD (pumpe duese aka unit injectors) and CR (common rail) owners: The
timing in PD and CR engines is determined electronically by the ECU. There is neither a
need nor an ability to check timing on the PD or CR engines using VCDS. There are no
graphs published for the simple reason that the timing is set using a dedicated VAG locking
tool when changing the timing belt :-)
